The worst among the possible causes is hardware damage. This is likely what triggers Wi-Fi that keeps dropping out or disconnected. Your iPhone has a physical antenna that is responsible for transmitting and receiving wireless signal and allows your device to carry out Wi-Fi and Bluetooth functions. If that antenna gets damaged from a drop or liquid damage, then that is what you need to fix first. This also denotes the need for service or tech repair.

Possible solutions and workarounds to deal with Wi-Fi issues on the iPhone

Considering that the problem is not the hardware, you can try performing some workarounds to fix the problem. You can refer back to the highlighted factors and start working on which you might think have caused your iPhone 7 Plus Wi-Fi to stop working as expected.
